Efficient geographic routing over lossy links in wireless sensor networks
Marco Zúñiga Zamalloa, Karim Seada, Bhaskar Krishnamachari, Ahmed Helmy
Article No.: 12
DOI: 10.1145/1362542.1362543

Recent experimental studies have shown that wireless links in real sensor networks can be extremely unreliable, deviating to a large extent from the idealized perfect-reception-within-range models used in common network simulation tools....

Optimal sensor placement for agent localization
Damien B. Jourdan, Nicholas Roy
Article No.: 13
DOI: 10.1145/1362542.1362544

In this article we consider deploying a sensor network to help an agent navigate in an area. In particular the agent uses range measurements to the sensors to localize itself. We wish to place the sensors in order to provide optimal localization...

Partial network coding: Concept, performance, and application for continuous data collection in sensor networks
Dan Wang, Qian Zhang, Jiangchuan Liu
Article No.: 14
DOI: 10.1145/1362542.1362545

Wireless sensor networks have been widely used for surveillance in harsh environments. In many such applications, the environmental data are continuously sensed, and data collection by a server is only performed occasionally. Hence, the sensor...

Reputation-based framework for high integrity sensor networks
Saurabh Ganeriwal, Laura K. Balzano, Mani B. Srivastava
Article No.: 15
DOI: 10.1145/1362542.1362546

Sensor network technology promises a vast increase in automatic data collection capabilities through efficient deployment of tiny sensing devices. The technology will allow users to measure phenomena of interest at unprecedented spatial and...

The theory of trackability with applications to sensor networks
Valentino Crespi, George Cybenko, Guofei Jiang
Article No.: 16
DOI: 10.1145/1362542.1362547

In this article, we formalize the concept of tracking in a sensor network and develop a quantitative theory of trackability of weak models that investigates the rate of growth of the number of consistent tracks given a temporal...

Near-optimal activation policies in rechargeable sensor networks under spatial correlations
Neeraj Jaggi, Koushik Kar, Ananth Krishnamurthy
Article No.: 17
DOI: 10.1145/1362542.1362548

We address the problem of optimal node activation in a sensor network, where the optimization objective is represented as a global time-average utility function over the deployment area of the network. Each sensor node is rechargeable, and can...
